GOOKINGl--RANGE SPECIFICATION forming part of Letters Patent No. 714,645, dated November 25, 1902.

l Application led December 13, 1901. Serial No. 85,748. (No model.)

To a/ZZ whom, t petty concer-7o:

Be it known that I,- HENRY J. MATELAS, of the city and county of Philadelphia, State of Pennsylvania, have invented an Improvement in Cooking-Ranges, of which the following is a specification.

My invention has reference to cookingranges; and it consists of certain improvements, all ofwhich are fully set forth in the followingspeciication and lshown in the .ac-l

companying drawings,I which form a part thereof. .,l

The object of myinvention is to provide a construction of range suitable for large hotel or restaurant purposes, Where a specially large capacity is necessary.V

My object is, further, to sb construct the range that the contents of the oven can be conveniently and quickl handled and its contents subjected to proper temperature for' very large and is provided with a rotary wheel-carrier structure, upon the periphery of which is hung a series of swinging shelves to receive the materials to be cooked, the said 4carrier being adapted to be rotated by hand from time to time to shift the position of .the materials within .the oven and also to bring the several shelves before a door through which the uncooked materials may be passed to the shelves andthe cooked materials taken `froml the shelves' and oven.

The cookinggases from the iii-es are controlled by suitable valves independently of the escape of the smoke products, which pass `up the chimney-due.'

the building by the outlet D4.

range, and B is the rear or cooking-oven portion thereof. Referring to the part A, I employ two iire'grates c and pots C, one on each side and with an oven D between them, the relative location of the parts being shown in dotted lines in Fig. 1. The coal to these iirepots is admitted through the lids S, of usual construction. lBelow the grates c are the ashpits C', having suitable doors C2 in front, and said ash-pits communicate with each other by flue d,passing under the intermediate oven D. The .smoke from the iires by regulation of the dampersDf e passes by smoke-fines D over the oven D, and thence by a chimney-fiue D3, and escapes to the chimney of may be provided With-`any of the ordinary and customary valves or dampers to control `the draft, such a valve being indicated at flues Dimmediately above the oven D. The

re-pots O maybe suitably lined with iirebrick or otherwise formed, as'desired. At the rear of the fire-pots C are the ilues E, leading into the chambers B of the large oven B, and

said iiues are provided with the valves e for controlling the heated gases passing to the oven. `Immediately at the rear of the gratos c and extending upward are cross-plates f, which act to retain the co'al Vandalso as deectors to direct the hot gases upward againstv the water-backs F in the act of escaping to the oven through the iiues E. These Waterbacks F may be of any suitable construction The Iiue D5 and in the usual manner heat the Water of g the hot-water boiler at P. They sustain the deflectors f.

IOO

. from the oven an article.

The oven-chamberB is verylarge, and preferably approximating a circle, the top being made circular to secure reverberatory action and the bottom being provided with thel inclined floors B2 to form the chambers B, opening at b into the lower central portion of the oven -chamber B. These chambers B/ receive the hot cooking gases through the valved fines E and deliver them to the bottom central portion of the oven. These iioors VB2are preferably made of soapstone or other and revolving with a shaft G, journaled in the front and rear walls of the oven at g. This wheel structure has at its periphery or extremity of its arms the cross-rods h, upon which are hung swinging trays H, which always retain their position under the action of gravity and at the same time permit the wheel structure to be rotated to shift the position of any tray within the oven and also tobring any tray and contents into position before the doorway7 Il when the doorl is opened, so that the cooked material may be withdrawn. To'hold the tray H from swinging at this time, I provide a pivoted arm P in the `side of the oven below the doorway L, which on being turned laterally under the tray holds it against downward motion and also against backward movement. This arm P is only used when inserting or removing The shaft G is provided on its end with a worm-wheel J, which is driven by a worm J on a horizontal shaft J 2. The shaft J2 is rotated by a wheel J 3, over which a chain K passes, to be operated by hand. Any other suitable power device may be employed to rotate shaft G and the oven wheel structure G.

N N are Iiues through the upper part of the oven-wall and open into hot-air flues O, above the oven, leading to the smoke-chimney outlet D4, before referred to. These fines, as

` shown, are so disposed as to heat as far as possible the upper part of the oven. The ii'ues N are provided with regulating-valves n, connected in pairs and operated by rods N', leading to the outside of the oven structure. While I have shown four flues N, Ido not limit myself to any number of ,lues, as they may be increased or diminished in number to suit the size of the oven. f

In the operation of myimproved range by properly adjusting the parts no smoke will pass into the oven, and in starting the same the dampers are all adjusted to send all the products directly to the chimney until the pass through the oven without injuring the contents thereof. When this latter condition takes place,the dam pers are regulated',so that the hot gases which are free from objection able constituents and excellently adapted for cooking purposes may pass through theflues E into the oven. The unconsumed carbon and objectionable constituents pass off from the upper part of the bed of fuel into the smoke-flue.

While I have shown two fire-gratos in the range, it is to be understood that I do not conline myself to the use of two such grates, as one alone may be employed, if desired.

I have found that the construction herein set out is excellently adapted in practice for the embodiment of my invention; but I do not conne myself to the details here shown, as they may be greatly modified without departing from the essential features of my improvements.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. Acookingrange having one or more iire pots and grates, combined with an oven, a smoke-flue from the top of the fire-pots, one or more gas-fines from the sides of the tirepots below the top of the bed of coal and opening into the oven, and one or more escapelines from the top of the oven.
